Field Type searching

Fields, or a custom Field Type, might contain or maintain data relevant for user searches. To make the search engine aware of the data in your Field Type you need to implement an additional interface and register the implementation.

Indexable interface

The Ibexa\Contracts\Core\FieldType\Indexable interface defines the methods below which are required if the Field Type provides data relevant to search engines.

getIndexData(Field $field, FieldDefinition $fieldDefinition)

This method returns the actual index data for the provided Ibexa\Contracts\Core\Persistence\Content\Field. The index data consists of an array of Ibexa\Contracts\Core\Search\Field instances. They are described below in further detail.


To be able to query data properly an indexable Field Type also is required to return search specification. You must return an associative array of Ibexa\Contracts\Core\Search\FieldType instances from this method, which could look like:

    'url'  => new Search\FieldType\StringField(),
    'text' => new Search\FieldType\StringField(),

This example from the Url Field Type shows that the Field Type will always return two indexable values, both strings. They have the names url and text respectively.


This method retrieves the name of the default Field to be used for matching. As Field Types can index multiple Fields (see MapLocation Field Type's implementation of this interface), this method is used to define the default field for matching. The default Field is typically used by the Field Search Criterion.


This method gets name of the default Field to be used for sorting. As Field Types can index multiple Fields (see MapLocation Field Type's implementation of this interface), this method is used to define default field for sorting. Default Field is typically used by the Field Sort Clause.

Register Indexable implementations

Implement Ibexa\Contracts\Core\FieldType\Indexable as an extra service and register this Service using the ibexa.field_type.indexable tag. Example from indexable_fieldtypes.yaml:

    class: Ibexa\Core\FieldType\Keyword\SearchField
        - {name: ibexa.field_type.indexable, alias: ezkeyword}

Note that alias should be the same as Field Type ID.

Search Field values

The search Field values returned by the getIndexData method are simple value objects consisting of the following properties:

Property Description
$name The name of the field
$value The value of the field
$type An Ibexa\Contracts\Core\Search\FieldType instance, describing the type information of the Field.

Search Field Types

There are many available search Field Types which are handled by search backend configuration. When using them, there is no need to adapt, for example, the Solr configuration in any way. You can always use custom Field Types, but these might require re-configuration of the search backend. For Solr this would mean adapting the schema.xml file.

The default available search Field Types that can be found in the Ibexa\Contracts\Core\Search\FieldType namespace are:

Field Type Description
BooleanField Boolean values.
CustomField Custom Field, for custom search data types. Will probably require additional configuration in the search backend.
DateField Date field. Can be used for date range queries.
DocumentField Document field
FloatField Field for floating point numbers.
FullTextField Represents full text searchable value of the Field which can be indexed by the legacy search engine. Some full text Fields are stored as an array of strings.
GeoLocationField Field used for Geo Location.
IdentifierField Field used for IDs. Basically acts like the string Field, but will not be queried by fulltext searches
IntegerField Field for integer numbers.
MultipleBooleanField Multiple boolean values.
MultipleIdentifierField Multiple IDs values.
MultipleIntegerField Multiple integer numbers.
MultipleStringField Multiple string values.
PriceField Field for price values. Currency conversion might be applied by the search backends. Might require careful configuration.
StringField Standard string values. Will also be queries by full text searches.
TextField Standard text values. Will be queried by full text searches. Configured text normalizations in the search backend apply.

Configuring Solr

As mentioned before, if you use the standard type definitions, there is no need to configure the search backend in any way. The Field definitions are handled using dynamicField definitions in Solr, for example.

If you want to configure the handling of your Field, you can always add a special Field definition to the Solr schema.xml. For Fields, the Field Type names used by the Solr search backend look like this: <content_type_identifier>/<field_identifier>/<search_field_name>_<type>. You can define custom dynamicField definitions to match, for example, on your custom _<type> definition.

You could also define a custom Field definition for certain Fields, like for the name Field in an article:

<field name="article/name/value_s" type="string" indexed="true" stored="true" required="false"/>
